■Multicast mode
• The master station and local station send data on the line in multicast mode in each send range.
• The CC-Link IE TSN Class A local station communicates data in the same communication range as the CC-Link IE TSN
Class B local station.

• Output from the master station
 The device is turned on by the sequence scan of the CPU module in the master station, and END processing is performed.
 The device status of the CPU module is stored in the link devices (RY, RWw) of the master station by link refresh.
 The status of the link devices (RY, RWw) of the master station is stored in the link devices (RX, RWr) of the local station on the same network by cyclic data
transfer processing.
 The status of the link devices (RX, RWr) of the local station is stored in the devices of the CPU module by link refresh.
• Input from the local station
 The device is turned on by the sequence scan of the CPU module in the local station, and END processing is performed.
 The device status of the CPU module is stored in the link devices (RY, RWw) of the local station by link refresh.
 The status of the link devices (RY, RWw) of the local station (station No.2) is stored in the link devices (RX, RWr) of the master station on the same network
and the link devices (RY, RWw) of the local station (station No.1) by cyclic data transfer processing.
 The status of the link devices (RX, RWr) of the master station is stored in the devices of the CPU module by link refresh.
